Catholic Commentary on Exodus 19

"You will be for me a kingdom of priests and a holy nation." (Exodus 19:6)

The Covenant at Sinai

Three months after leaving Egypt, Israel arrives at Sinai. God calls to Moses from the mountain: tell the Israelites: you yourselves have seen what I did to Egypt and how I carried you on eagles' wings and brought you to myself. Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession, for the whole earth is mine. You will be for me a kingdom of priests and a holy nation. The Catechism identifies this verse as the foundational description of Israel's vocation, fulfilled in the Church as the holy nation called out of every people to be the priestly community that mediates the knowledge of God to all nations (CCC 1546). The election is not for privilege alone but for service: a kingdom of priests, mediating between God and the nations.

Moses comes down and relays the LORD's words. The people answer together: we will do everything the LORD has said. God tells Moses to consecrate the people for two days, washing their clothes, setting limits around the mountain. On the third day the LORD will come down on Mount Sinai in the sight of all the people. The third day arrives: thunder and lightning and a thick cloud and a very loud trumpet blast. The whole mountain is covered in smoke because the LORD has descended on it in fire. The mountain trembles violently. The people tremble too. The Catechism calls this theophany at Sinai the supreme Old Testament revelation of the holy God whose presence produces both awe and desire (CCC 2059).

Living the Word

Brothers and sisters, a kingdom of priests and a holy nation. This is the description of the Church in 1 Peter 2:9, drawn directly from Exodus 19. Every baptised person shares in this priestly calling: not to perform ritual sacrifice but to offer the whole of life to God, to stand between God and the world in intercession, to be the community through which the knowledge of the holy God reaches those who do not yet know him.

Prayer

Lord God, you brought us on eagles' wings to yourself and made us your treasured possession. Let us be a kingdom of priests and a holy nation, consecrated for the service of your purposes in the world. Through Christ our Lord. Amen.

Israel at Mount Sinai
In the third month, on the same day of the month * 19:1 Hebrew In the third month, on the same day; that is, two months after leaving Egypt; see Numbers 33:3. that the Israelites had left the land of Egypt, they came to the Wilderness of Sinai. After they had set out from Rephidim, they entered the Wilderness of Sinai, and Israel camped there in front of the mountain.
 
Then Moses went up to God, and the LORD called to him from the mountain, “This is what you are to tell the house of Jacob and explain to the sons of Israel: ‘You have seen for yourselves what I did to Egypt, and how I carried you on eagles’ wings and brought you to Myself. Now if you will indeed obey My voice and keep My covenant, you will be My treasured possession out of all the nations—for the whole earth is Mine. And unto Me you shall be a kingdom of priests and a holy nation.’ These are the words that you are to speak to the Israelites.”
 
So Moses went back and summoned the elders of the people and set before them all these words that the LORD had commanded him. And all the people answered together, “We will do everything that the LORD has spoken.”
 
So Moses brought their words back to the LORD.
 
The LORD said to Moses, “Behold, I will come to you in a dense cloud, so that the people will hear when I speak with you, and they will always put their trust in you.”
 
And Moses relayed to the LORD what the people had said.
 
10 Then the LORD said to Moses, “Go to the people and consecrate them today and tomorrow. They must wash their clothes 11 and be prepared by the third day, for on the third day the LORD will come down on Mount Sinai in the sight of all the people.
 
12 And you are to set up a boundary for the people around the mountain and tell them, ‘Be careful not to go up on the mountain or touch its base. Whoever touches the mountain shall surely be put to death. 13 No hand shall touch him, but he shall surely be stoned or shot with arrows—whether man or beast, he must not live.’ 19:13 Cited in Hebrews 12:20
 
Only when the ram’s horn sounds a long blast may they approach the mountain. 19:13 Or may they go up on the mountain
 
14 When Moses came down from the mountain to the people, he consecrated them, and they washed their clothes. 15 “Be prepared for the third day,” he said to the people. “Do not draw near to a woman.”
The LORD Visits Sinai
 
16 On the third day, when morning came, there was thunder and lightning. A thick cloud was upon the mountain, and a very loud blast of the ram’s horn went out, so that all the people in the camp trembled. 17 Then Moses brought the people out of the camp to meet with God, and they stood at the foot of the mountain.
 
18 Mount Sinai was completely enveloped in smoke, because the LORD had descended on it in fire. And the smoke rose like the smoke of a furnace, and the whole mountain quaked violently. 19 And as the sound of the ram’s horn grew louder and louder, Moses spoke and God answered him in the thunder.
 
20 The LORD descended to the top of Mount Sinai and called Moses to the summit. So Moses went up, 21 and the LORD said to him, “Go down and warn the people not to break through to see the LORD, lest many of them perish. 22 Even the priests who approach the LORD must consecrate themselves, or the LORD will break out against them.”
 
23 But Moses said to the LORD, “The people cannot come up Mount Sinai, for You solemnly warned us, ‘Put a boundary around the mountain and set it apart as holy.’ ”
 
24 And the LORD replied, “Go down and bring Aaron with you. But the priests and the people must not break through to come up to the LORD, or He will break out against them.”
 
25 So Moses went down to the people and spoke to them.
